In macbeth ACT 3 scene 6 Which is the suffering country and why is it suffering?

Lennox says: "Some holy angel Fly to the court of England and unfold His message ere he come, that a swift blessing May soon return to this our suffering country Under a hand accursed!" Lennox is a Scotsman, so "this our suffering country"is clearly Scotland, suffering under the "hand accursed" of King Macbeth.
